Barry Rosenstein’s JANA Partners liked grocery chain Supervalu Inc in a big way in the first quarter, while Philippe Laffont’s Coatue Management lost its stomach for the company’s shares.

Regulatory filings revealed that JANA, a hedge fund with US$ 5.5 billion in assets, picked up some 14 million shares of Supervalu in the quarter ended March 31. For Laffont’s US$ 9.5 billion firm, however, it was a different story, as the hedge fund dumped all of its roughly 10 million shares.
